Lists of UK Businesses by Sector: Where to Get Them and What's in Them

Lists Of gives you straight answers about lists of UK businesses: how many there are in each sector (from the official registers), which free sources exist and what their terms let you do with them, and the business lists you can buy, with exact counts of addresses, phone numbers, named contacts and email addresses.

Short answer

Official registers tell you how many businesses there are, but most are for looking businesses up, not for marketing. For a list you can filter by area and use for post, phone or email, you need a licensed business list. Ask for a free count and sample first, and check the email coverage: in some sectors most records have no named email.

  • 1,486,280 UK business records in more than 2,000 categories
  • 1,219,031 named contacts and 454,737 named contact email addresses
  • Official counts and free sources checked for every sector guide
  • Free count and sample records before you buy

Lists of UK businesses: sector guides

Each guide answers the question people actually ask: where can I get a list of these businesses, and what will I get? It covers the official count, the free registers and their limits, the contact details available to buy, who makes the decisions, and the marketing rules that apply to that sector.

Lists of UK businesses: questions

Where can I get a list of UK businesses in a particular sector?

Start with the official register for that sector if there is one (for example a regulator's register or a government directory). Registers are usually free to search but are built for checking one business at a time, and many say you can't use them for marketing. For a marketing list you can filter and download, buy a licensed business list: we hold 1,486,280 UK business records in more than 2,000 categories.

Can I get a list of businesses with the decision maker's email address?

Sometimes. Of the 1,486,280 business records we hold, 1,219,031 have a named contact and 454,737 have that person's email address, but coverage varies a lot by sector: each sector page shows the exact figures. Where named emails are thin, post and phone reach far more of the sector.

Is it legal to buy a business list and market to it?

Yes, with rules. Post is allowed to any business. Live sales calls must be screened against the TPS or CTPS. Marketing emails and texts can go to companies without prior consent if you identify yourself and offer an opt-out, but sole traders and ordinary partnerships need to have consented first. Where a record names a person, UK GDPR applies too.

Why don't your counts match the official number of businesses?

Official figures count different things: a regulator counts registered people or premises, ONS counts workplaces registered for VAT or PAYE, and Companies House counts companies. Our counts are the records we hold that you can buy. Each sector page shows the official figures side by side with ours.
